The recuperating rocker (who was hospitalized in recent months with a brain hemorrhage and then a “warning stroke”) will perform with the teen queen “Every Rose Has a Thorn,” the Poison song Cyrus covers on her new album.

The ‘GMA” duet represents the first time Bret and Miley are performing the song live together.

To maximize the pop-culture overload of the outing, Kate Gosselin will accompany on drums while Charlie Sheen works the keyboards. (I kid!)
